Be it hewn that ll, Jumps M, ZIMLIOH, a citizen of the United States, residin at Mobile, in the county of Mobile and tate of Alabama, have invented certain new and useful Improvements in Agricultural Machines; and ll do hereby declare the following to be a full, clear, and exact descriptlon of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements 1n agricultural machines and more particularly to tractors or hand tractors by which a variety of agricultural'operations may be performed such as c ultlvatmg between growing crops, for makm rldgcs and cultivating crops planted on ri ges such as the truck crops in regions' of great ralnfall.

Other objects of the invention are to slmplify the tractor, reduce the expense of its manufacture and the expense attendant upon its use in the fields, to render more compact and effective the a icultural implements and the frame to w ich they are attached, and'in general to provide a more satisfactory and eiiicient machine for gen-l eral a ricultural purposes.

' With the foregoing and other objects in view, the inventlon will be more fully described hereinafter, and will be more particularly pointed out in the claim appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 10 is a plan view of the secondaryV frame and plows detached from the remainder of t e apparatus.

0 Referring more particularly to the drawo 1n s, 1 and 2 designate two beams, preferab y of angle iron, which are braced together andy held in substantially arallel though spaced relation to constitutet emain frame of the tractor. These two beams 1 u and 2 sup ort at their front ends an internal com ustion or other engine 3. This engine is only conventionally shown as it forms no part of the present invention. Suiice it to say that the engine drives the pinion 4 which is disposed in mesh with the gear wheel 5 made fast to a shaft 6 which 1s journaled in appropriate bearings in the main frame and carries a sprocket 7 en ged u by a chain 8. This chain drives a Fasi' er sprocket 9 fixed on the axle 10 journals in" t e bearing blocks 11 secured beneath the horizontal flanges of the angle beams. The axle also passes fixedly through the single .o ground wheel 12 which is provided with traction-lugs 13. The bearing blocks 11 are secured to the angle beams by the bolts 14 which pass adjustably through the slots 15 made in the beams 1 and 2. The slots, are n elongated in the direction of movement of the tractor and are for the purpose of permtting of adjustment of the bearing blocks desired a screw 16 having threaded engage-.

- ment with a xed lug 17 is made for engagement with each block 11 for the -purpose of thrusting the block rearwardly when the screw 16 is turned in one direction.

The main frame is provided with handles 18 suitably bolted or otherwise secured thereto at an intermediate part preferably j 'ust slightly rearward of the axle 10 and t ese handles diverge rearwardly and extenddiagonally upward being appro riately braced as indicated at 19 and 20. T e main frame and the handles also support the legs 21 u on which is carried the platform 22 and uel \tank 23 and a tool box 24 are supported upon theipiatform 22 as shown in Figure 1. The englne3` is arranged to drive the tractor through the arrangement of gearing just referred to and a clutch 25 is disposed preferably between the small sprocket 7 and the `gear wheel 5 for the purpose of disconnecting the engine whenever desired. The movable element of the clutch is connected to a bell crank lever 26 fulcrumed at an appropriate point of the main frame andconnect- ,ed for operation to a link 27 which extends to a hand lever 28 carried upon the rear handle brace 19 where it will be convenient for operation. The lever is provided with -a hinged latch 29 adapted to coo erate with the clutc may be latched in a connected or disconnected position.

At the rear end of the main frame is a solid casting 31 riveted or otherwise secured between the beams 1 and 2 and adapted to receive the turning ,pin 32 of the caster wheel 33.

Under the main frame is supported a secondaryframe such as shown m Figure 10 composed of the angle bars 34 and 35 spaced apart and suspended from the beams 1 and 2 of the main frame by pairs of front and rear links 36 and 37. The lower ends of the links pivot about rods 38 and 39 which extend transversely across between the members of the `secondary frame.. The up er ends of the links 36 and 37 are pivotailly mounted to bolts 40 and `41 carried by the vertical webs of the beams 1 and 2. The suspension of the secondary frame is such as to admit of the adjustment vertically thereof together withthe a ricultural implements that the secondary rame is designed to carry. These agricultural im lements may be of a varied character an infact the arrangement is such as to admit of receiving the various known earth working implements. For ridge cultivation however I prefer to employ the arran ement and species of implements hereafter escribed.

rforated segment 30 w ereby thel bent end 43 extendin parallel with the links 37' and being couple at its lower end to the rod`39. A. spring latch 44 is carried by the lever 42 and cooperates with the tooth segment 45 upon the main frame whereby to hold the lever and the secondary frame in the adjusted position. rlhe secondary frame supports at its forward ends two plows 46 and 47 one right handed and the other left handed placed on opposite sides of the longitudinal center. The stocks 48 of the plows are riveted or otherwise secured to the rails 34 and 35. A-central plow 49 is placed in back of the right and left plows and this central plow is a middle buster with larger mould boards.

In Figures 6, 7 and 8 is shown a harrow attachment for the secondary frame in which 50 designates the harrow points or teeth which are arran ed with their innermost points at a low evel and progressing upwardly and rearwardly from the inner to the outer points. These harrow points are separated the distance between the rows and they are carried as shown in Figure 8 by double braces '51 and 52 which join together at their lower ends where they connect with the points. The upper divergent ends are turned mutually toward one another as indicated at 53 and 54 and conform generally to the angle rails 55 and 56 which form portions of the harrow frames. These an le rails are strengthened at suitable points y the transverse brace 57 which are riveted or otherwise secured thereto, the rivets or other fastenings also passing through the angled ends 53 and 54^ of the lparts 51 and 52. The harrow frames are t us virtually parallelograms and the frames are held in the inclined positions shown b bars 58 and 59 which are bolted or otherwlse secured to the parts 34 and 35 of the secondary frame. The bar 58 is substantially horizontal throughout its length being bent up lonly where itk is secured to the harrow rame but the other bar comprises an elongated-diagonal portion sloping up to meet a hi her point of the harrow frame. The secon ary frame is adapted to carry two such harrow frames one of which may be slightly in advance or in rear of the. other or in other words the two harrow frames may be oil'set with' respect to each other but they are similar as to construction and as to the manner of their connection with the secondary frame.

Now in Figure 8 there is shown a marking device resembling somewhat the harrows and. provided with teeth 60 similar to the harrows but bein three in number,'one tooth in the middle an the other two teeth being disposed at the ends of a long bar 61 which extends transversely of the secondary frame and is bolted or otherwise removably secured thereto by the fastenings 62. The

-outer points or blades'O may be made ad- I "justable if desired.

Now referring to Fi es 3, 4 and 5 as y here shown a fertilizer istributor comprises cylinders axially on the shafts the grooves or chambers 68 are made larger or smaller in accordance with the portions thereof remaining in connection with the throat. In this way the distribution of the fertilizer is regulated. The shaft 70 is carried in l bearings 71 supported upon straps A72 which incidentally also support the rece tacles 63.

The straps 62 are carried by a bar 3 mounts ed transversely across theA machine. On the shaft' is a sprocket wheel 74 driven by a chain indicated at 75 in dotted lines from asprocket 76 on the axle l10 as shown in Figures 2 and 3. y p

The work is accomplished as follows First the land is la1d off by means of the marker shown in Figure 9. At each turn in the field, the inner point is made to pass exactl over the last line marked, thus two new l1nes are made. The laying of of the field is important, for the ridges must be evenly spaced for the perfect work Vof the cultivator.

The second operation is the vmaking of the ridges. The marking device is removed and the plows are put in place. Tlie lows are set at the pro er de th and a ri ge is thrown up .on eit er si e of the machine. By simple side' pressure on the handles the machine is easily guided. At the end of the row, the driving mechanism is thrown out of gear by the lever 28 and the plows may be `raised out of the ground .either'by working the lever 42 or by simply liftlng them out by the handles, the englne helping in this on account of its weight in front. The turn about is thenk easily made by pushing the handles sidewise if the plows are dlsenga ed, .or by walking around with the hand es lifted up if the. plows remain inl position. Every turn results in the making of a ridge. The old way with a mule requires three turns, two with the clipper plow, andv one 'with the middle buster.

For. the cultivation and fertilization of l the ridges, two cli per plows are removed and in their stea the side harrows are mounted on the secondary frame. One of them is mounted a few inches in front of the other in order that possible `bundles of weeds or other obstructions may not be rter thex from the sides of the ridgesandputs it up.

rolledi and packed on the main frame-im-lmediate behlnd the har'rows and in front of the middle buster. L

The harrows are set so as to cultivate the sides of two nei hboring ridges at the depth wanted. The ertilizer attachment drops the fertilizer immediately behind same ata rate sproc etwhee1s 74 and 76. The middle bustakes the soil that has fallen down again in the same way as when the ridges were first made. f

In the entire South, in all the Gulf States, the excessive rain fall calls for ridge cultiva.- tion, es ecially for trucking crops. So far no mac ine has successfully taken the place of the mule in this work. Such other machines as have been ex erimented with are all for cultivation on t elevel. This type of cultivationmay also vbe achieved with the present machine by the use of proper implements. t.

The present machine however, accomplishes at one assage what `otherwise would re uire from't ree actions in the recess of ma 'ng the rid es, to five actions 1n the cultivation thereo First. Passing withv the side harrow up one side.

Second. Passing down on the other side.

Third. Application of fertilizer by hand on one side.

` Fourth. Application of fertilizer on the other side.

Fifth'. Passing with middle buster restor-l rovided by the relative size of theK Third. Gomg over this middle strip with the middle buster, finishing the ridges. f

On an average, therefore, the invention would save three trips, doin the work in one fourth the time and inci entally doing away with three mules and three farm hands out of every four and nally replace the fourth mule by the tractor.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specilicall described embodiment of this invention wit out departing from the spirit thereof, such chan s and modifications being restricted cul; by the Scope of the following cla-im.
